Needs attention❌ Critical: 13px body text is too small. Increase to at least 14px.
⚠️ Tight line spacing (1.00). Consider 1.4-1.6 for better readability.
✅ Good hierarchy: Clear distinction between headlines and body text.
✅ Good performance: Using 2 font families keeps load times fast.
✅ Consistent design: Single font family with weight variations is a modern best practice.
⚠️ Cramped layout: 13 elements lack adequate spacing.
